[alsa-devel] [PATCH v3 1/2] ASoC: soc-core: Remove unneeded dentry member from snd_soc_codec
There is no need to have the *debugfs_reg dentry member as part of the snd_soc_codec structure as its only usage is inside soc_init_codec_debugfs().
Use a local dentry variable instead.

The check of IS_ERR or NULL pointer can be replaced by IS_ERR_OR_NULL(), which helps readability.

The patch
ASoC: soc-core: Use IS_ERR_OR_NULL()
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
